3 Claims.

My present invention relates to a combined diversion and hot-coldcontrol device.

More particularly, my invention relates to a fixture applicable to beconnected with pipe lines serving heated and unheated water, and havingappropriate valves for controlling the relative quantities of suchheated and unheated water, and passage means Within or directlyassociated with the casing and provided with valve means for controllingdually the direction and the extent of the flow of the inter-mixedheated and un. heated water, to either of two appropriate locations,such as tub and shower, tub and basin, shower and basin, etc., withwhich the fixture is piped.

The most preferred forms of my invention embody a casing, nipples andchambers extending into the casing for the respective hot and cold pipelines, valve seats respectively disposed within the casing for suchchambers, movable valve members, preferably appropriately designated hotand cold which cooperate with such valve seats for the control of inflowof the heated and unheated water, suitable means for eiectivelyintermixing the heated and unheated water with-'-- in the interior ofthe casing, passage means for connection to the lines of piping leadingto two diversified locations, such passage means having port meanscommunicating with the interior of y the casing, and valve means forsuch passage means provided with a movable valve member for duallycontrolling the direction of diversion of the ow of the'intermixedheated and unheated water and the extent of such ilow.

The invention, as is apparent, is not restricted to the control of waternor to the control of two streams of relatively heated water, but isapplicable to the admixing of any two streams of liquid and the controlof the divergent ow and the extent of such divergent now.

An advantageous feature of certain types of embodiments of my inventionresides in the combination with the casing into which the respective"hot and icold water, or other two uids, now, of outflow passage meansarranged to be connected to piping leading to two locations or use,

and valve means for such outflow passage means affording, firstly,communication between the in terior of the casing and the outflowpassage means, secondly to select the terminus of the now, and thirdlythe extent of such diverted now.

Further features and objects of the invention will be more fullyunderstood from the following detail description andthe accompanyingdrawings, in which Fig. 1 is a front elevation of a preferred form Yofmy invention, illustrated as adaptable to a hot-cold-shower-t fixture;

Fig. 2 is a vertical sectional elevation on the broken section line 2-2of Fig. 1;

Fig. 3 is a. vertical section online 3-3 of Fig. 2; Fig. 4 is a detailsectional elevation on line 'fa-4 of Fig. 2; and

Fig. 5 is a detail sectional elevation on line 5-5 of Fig. 2.

Referring to the illustrated preferred form of my invention, the casingI0 may be of any sintable coniiguration, that illustrated in Figs. 1 and3, being generally triangular.

At the lower end, as appears in Figs. 1, 2 and 3, 15 is provided thenipple portion II for connection with piping supplying heated, that ishot, water, and the nipple portion I2 for connection with piping forsupplying unheated, that is cold, water. The nipples II and I2 areindicated as 20 provided with threading and therefore anording yconnection with piping -by threaded pipe fittings;

however, such connection may be by sweat joint or any other form ofpresent day or other approved type of connection. The nipple portions 25I l, I2 communicate with the respective chambers I3, I4, in turnterminating at their valve seats I5, I6, respectively, see Figs. 2 and3.

Referring to Figs. 2 and 3, the chamber I3 communicates through theopening of its valve seat 30 I5 with its outflow chamber I1, preferablyprovided with oppositely directed outflow ports I'la, Ilb, orequivalent, leading into the interior of the casing I0. The control ofthe outow through the opening of the valve seat I5 is had by any suit-35 able valve means. As illustrated in Fig. 2, such valve meanscomprises the movable valve member I8 carried by the rotatable stem I9,secured as by a screw 20 to its operating handle 2l.

Correspondingly, the outow chamber com- 40 municating through theopening of the valve seat I6 of the chamber Ill is provided withsuitable ports I8a., lab, see Fig. 3, preferably projecting thedischarge in oppositely directed streams, thus cooperating with theoppositely directed ports 45 I'la and Ilb to effectively intermix thetwo streams within the casing l0. For such purpose, it will be observed,the ports Ilb and Iilb are directed in a downward direction, and theports Ila and Ilia are directed in a general upward 50 direction, thusprecluding any stratiiication of unheated water in the lower portion ofthe casing and heated water in the upper portion of the casing.

Directly associated with the casing I0, and 55 preferably a lmitary parttherewith, I provide passage means 22 and a valve 23 therefor, suchpassage means communicating, as through a port 24, see Fig. 2,specifically through the movable valve member 23a, with the interior ofthe casing l0. The passage means 22 is further provided with extensions25, 26, for connection respectively with piping leading to any twoappropriate locations of discharge or use, such as one piping leading toa shower and the other piping leading to a tub, for which particulardiverting use the xture illustrated in Fig. 1 bears the legends "Shower"and Tub.

The terminalor nipple portion 25a of the extension 25 and the nippleportion 26a of the extension 26 may be threaded, as indicated in Figs. 1and 3, or may be connected to the piping by sweat joint or any othersuitable form of connection.

The stem 23a of the diverting valve 23 is provided with any suitableform of operating handle 21, desirably to have an index portion 21a, seeFig. 1., and thus indicate the direction of diversion effected by thevalve 23 at its `various positions of setting. For such or otherpurpose, the discharge port 23h of thediverting valve 23, see Figs. 2and 3, is arranged in operative position to correspond to the indexportion 21a. In the position illustrated in Figs. 2 and 3, the dischargeport 23h communicates with the extension 25 of the passage means 22,thus directing the ow of the uid from the interior of the casing I0 intothe piping leading, in this instance, to the shower, the path of owbeing specifically through the iniiow port 24, thence through the bodyof hollow movable valve member 23, thence through the discharge'port23b, into and through the extension 25 of passage means 22, andthus intothe piping leading to the shower.

It will be further observed that rotationof the movable valve member 23continued from its position shown in Figs. 2 and 3 effects more and morethe restriction of the extentof eective communication of its dischargeport 23h with the extension 25 of the passage means 22, thus restrictingthe flow to any desired extent. Correspondingly, upon rotating theoperating handle 21 to move its index portion 21a, say one hundred andeighty angular degrees from its position as shown in Fig. l, thedischarge port 23b is brought into more and more e`ective communicationwith the extension 26 of the passage means 22, thus diverting the waterto corresponding extent of iiow to the Tub.

As illustrated inthe drawings, the discharge port 23h is preferably of arange of angular opening to provide at ay setting iiow, and of regulatedextent, exclusively into either of the two extensions and thecorresponding location of ultimate discharge.

It will be observed that the general triangular conguration of thecasing I0, coupled with the location of the diverting valve 23 towardthe upper apex of such triangular outline, see Fig. 3, the Vdischargesof the hot and the cold valves being located at the base of suchtriangular configuration on opposing sides of the port 24, and atsubstantially equal distance from the diverting valve, is eiective forinsuring complete intermixing of the two ows into the easing andsubstantial uniformity of temperature through the port 24, for any givensettings ofthe inflow valves I 5 and I 6 and the outow valve 23.

Aa appears from the above, thespecific construction and the material ofthe detail parts of my invention may be selected as preferred andpursuant to the requirements of commercial operation 4conditions wellunderstood by those skilled in the art. Desirably, the casing and thevalve and other parts of embodiments of my invention are formed ofmetal, either cast to desired forms or of suitably shaped wrought metalor equivalent.

To afford convenience of assembly, and also 1 for disassembly in thecircumstance of repair, inspection or the like, it is convenient toprovide a face plate I 0a of stamped or shaped wrought metal, separatefrom the casing proper I0, in which form of manufacture the front facepor- 1 tion Illb of the casing proper I0 may be provided with nippleformations Illc, |0c for the respective inow valves I6, Il and a similarnipple formation ltd for the outflow or diversion valve 23,- a gasket 30being interposed between each 2 movable valve stem Within its nippleformation, and locked by a washer or lock-nut 3| or equivalent, as isindicated in Fig. 5 with respect to the outow or diversion valve 23.

Such front plate Illa may desirably be stamped 2,1 with the legends Hot,Cold", Shower and Tub, or equivalent designations.

Coacting with such front plate Illa, I may provide for each movablevalve stem a hollow boss 32 having an outer terminal portion 32' of 31 ysquare or otherpolygonal contour for securement thereto by a set screw20 of the respective operating handles (2l, 2|, for the two inow valvesand 21 of the outow or diversion valve), each handle being provided witha correspondingly 34 contoured opening, and* each boss 32 has an inner'terminal portion 32a of squared or other polygonal contour, receiving acorrespondingly contoured outer stem portion, see 23a. Fig. 4, of themovable valve stem 23a, whereby upon grasping 4U and turning anoperating handle, the torque is transmitted through the statedrespective mating polygonally contoured parts, the set screw 20 servingmerely -to-hold the stated puts in operative relation.

Whereas I have described my invention by reference to specic formsthereof, it will be understood that many changes and modications may bemade without ,departing from the. spirit of l the invention.
